L
ow-temperature solid oxide fuel cell (LT-SOFC) is one of the most favorable energy conversion systems that are need of
hour. The advancement in field of LT-SOFC requires a highly efficient, oxygen permeable, good electro-chemical cathode.
The SCF (Sr0.3Co0.6Fe0.1) oxide composite cathode was prepared by environmental friendly sol-gel method. The crystal
structure of prepared materials was analyzed by x-ray diffractometry, while structural characteristic were studied by Fourier
transform infra-red spectroscopy (FTIR). The particle size was calculated by Scherer’s formula and found to be 36 nm. The
results were also confirmed by SEM images. The prepared material showed porous coral reef like surface morphology in
recorded scanning electron micrograph. The activation energy was calculated by Arrhenius curve that is 3.0×10
-2
eV and
highest electronic conductivity measured and calculated was 24.01 S/cm. SCF oxide cathode was tested for potential LT-SOFC
between the range of 450ºC-650ºC temperature. The maximum current density and power density obtained at 650ºC was 887
mAcm-2 and 110 mWcm-2 respectively.
